I have to say that the addresses found by the scouts are all very good, but we still need to choose the best ones.
No matter how modern seagoing ships are built, there will definitely be no shortage of metal objects on board, so you still need to look for places with fire sources. .
We understand that Yuntong County has used coal extensively, so this factor must also be taken into consideration, as well as the structure of the land. It will not work if it is all sand, as it will easily cause collapse.
The hull of the ship is huge, and the dock is a large, immovable rack. Only by relying on such a rack can the ship be perfectly assembled on the shore.
Another thing is also very important. The transportation is convenient. No matter what you need, it can be delivered as soon as possible. That is really perfect.
Whenever you go to sea, you must have a lot of time, and there is a city nearby for easy supply.
Tang Long didn't know that according to the current perfect screening method, the technology tree of the shipyard actually appeared a thousand years earlier, as well as the advanced manufacturing technology of ancient sea ships.
Zhang Yumeng suggested the rudder, and Yang Gan provided the watertight compartment and keel structure.
The rudder is a device installed behind the stern of the ship to control the course. Although the rudder is a small device, it can make the huge hull move freely.
The secret is that if a sailing ship wants to turn left, it must deflect the rudder to the left at an angle, and the water flow will generate a pressure on the rudder surface, that is, rudder pressure.
The rudder pressure itself is very small, but it is far away from the ship's center of rotation, so the torque that causes the ship to rotate is relatively large, and the bow will turn to the left accordingly.
The emergence of the rudder will rewrite the history of navigation in the world and provide key technical conditions for navigators to conduct ocean voyages.
Watertight cabins, also called waterproof cabins, are the safety structural design of ship cabins. They are located inside the hull and are multiple independent cabins separated by watertight bulkheads inside the hull.
When a ship encounters an accident and a small part of the cabin is damaged and flooded, other watertight compartments that have not been affected can also provide buoyancy to the ship and reduce the risk of immediate sinking.
In addition, watertight compartments can also be planned as multi-purpose spaces, such as housing people, storing goods, and even weapons.
This technology did not appear until the Northern and Southern Dynasties. Yang Qian has now developed it. It can be said that the technology tree of this line has been lit up thousands of years earlier.
I don’t dare to hope for the stars and the sea, but the future overlord of the sea will undoubtedly be the Central Plains.
As for the keel structure, it is more complicated. Yang Qian only knows one or two types. In fact, the keel can be divided into six types.
Keel, side keel, ribs, ribs, bilge keel.
Each type of keel has different functions, just like the keel.
It is a longitudinal member that connects the bow pillar and the stern pillar in the center of the base of the hull. It mainly bears the longitudinal bending moment of the hull. When making a ship model, it is necessary to choose rectangular cross-section pine strips with straight wood grain and no knots.
Dragon ribs: Dragon ribs are longitudinal members on both sides of the hull. Together with the ribs, they form a network structure to fix the side plates of the ship and increase the structural strength of the hull. The dragon ribs of ship models are usually made of rectangular pine strips. Make.
These three advanced technologies, even two thousand years later, sea ships are still built on this basis.
Don't doubt the inheritance and learning ability of professionals. Yang Qian and Zhang Yumeng just instilled all the shipbuilding knowledge they knew into Tang Long. In fact, both of them ignored one thing.
The two of them were really not familiar with ancient warships, so they often used the analogy of modern cruise ships. After all, even modern warships had only been seen in movies, but they had never even touched the real thing.
After several days of careful speculation, comparison, and screening, Tang Long hurried to Yang Qian's residence with three official documents.
"Your Majesty, after a few days of screening, we found that these three places are very suitable for building a shipyard in terms of transportation, supplies, woods and sites."
Tang Long spread the three official documents and topographic drawings on the desk, and Yang Qian also looked at them carefully.
After a long time, Yang Qian breathed a sigh of relief. It seemed that he had found a treasure this time.
Take out a mineral distribution map from the bookshelf and compare it carefully.
After a while, Yang Gan pointed to an official document and said, "How about choosing Wanghai County in Haichao County?"
Tang Long nodded and said, "The location here is good. The most important thing is the convenient transportation. There is an official road that leads directly to Haichao County, and there are no reefs. I just don't know how the minerals are?"
Yang Gan threw him a drawing of the known mineral distribution points. Not only were there marks on it, but the current situation of the minerals and the ownership of the property rights were also recorded.
A smile gradually appeared on Tang Long's face. This place is really perfect. There is almost no place nearby that can compare with this place.
"Okay, let's settle it then."
Following Yang Gan's order, a large number of slaves, supervisors, grain, and horses began to operate. Of course, this was not a departure, but a refit.
That's Haichao County over there. Although I am the governor of Yuntong County, I always have to say hello first when going to other people's places.
Yang Gan ordered a hundred troops and took Krisna, Belika, Ran Jing and Tang Long with him to set off.
It’s still the same thing, ancient times are no better than modern times, even if you are going to a place hundreds of miles away, if you don’t prepare salutes and food.
If you have to sleep in the wild, you may also have to go hunting. Who can bear it when there is no human habitation in a place with a radius of hundreds of miles.
This time we were fully prepared, with dozens of carriages carrying not only food and grass, but also a large amount of canned meat and canned fruits.
The replacement weapons and armors are indispensable, as well as the medicines prepared by Ge Zhao and Ge Xiuming and Yang Gan's secret weapons.
Just when a group of people were preparing to set off, a tall and beautiful figure, carrying a strange spear more than two meters long on his back and a sword on his waist, was waiting for everyone at the entrance of Zhuangzi.
Yang Gan rode on the back of the rhinoceros and asked curiously, "Master? What are you doing?"
"I'm bored staying here and want to go out for a walk. I heard you went to Haichao County and I also want to see the sea." Cao Wushuang said lightly.
Yang Gan smiled and said, "Master? Didn't Yue have water before?"
"The Yue Kingdom is located in the Kuaiji County of Xingguo. How come there is no water? There is water everywhere, but I have never seen the sea. I heard that the sea water is salty, and I want to see it."
Cao Wushuang said, a hint of cunning flashed in his eyes.
Yang Gan shouted to the back, "Come here, get me a good horse."
"No, I'll ride with you."
Before Yang Gan could say anything, Cao Wushuang jumped up in the stirrups and sat firmly on the rhino's back.
"This~~Master, we are not in line with etiquette."
Cao Wushuang sat behind him, which made Yang Qian unable to lean on him and made him very uncomfortable.
"Hey, you're still telling me about etiquette. I guess you've never done anything related to etiquette." Cao Wushuang mocked.
The corner of Yang Gan's mouth twitched fiercely, and what he said seemed to be saying that he never did anything with people.
Yang Gan looked back, and sure enough he saw the spear behind Cao Wushuang. The cold light made him feel chilled all over.
"Where did the xa on your back come from? Judging from the pattern, it must be made of patterned steel." Yang Gan asked casually.
Cao Wushuang stretched out his hand and touched his back, his eyes showing satisfaction, "Zhang Xiaoniang took me to the foundry to make it. It is very sharp. With a light poke, it can pierce the leather armor and close it."
Yang Gan used to think that this weapon was a gun, but later he learned that this gun-like thing was called a hoe.
Of course, other vassal states also have it, but they have different names. Some are called beryllium and some are called 铦. In fact, they are the same thing.
This weapon is similar to a sword. Its sharp part is like a palm-wide bronze sword, but the length of the pole is four meters upward.
As the saying goes, the crossbow is in front and the gong is behind. The gong is this kind of weapon. Of course, there are also some that make two curved branches at the position of the sword grid for blocking. This is called a gong.
The spear used by Yang Qian was very sharp, and its main property was to break armor. Cao Wushuang's spear was obviously custom-made, otherwise there would be no weapon lower than four meters.
The length of more than two meters can be used in daily life, and can satisfy both horse and foot battles. It is just suitable for Cao Wushuang's current state.
Yang Gan sometimes has obsessive-compulsive disorder. He likes soldiers to use weapons of the same specifications. Hogs are hoes, crossbows are crossbows, knives are knives, and swords are swords.
Unfortunately, the weapons in the Central Plains have always been complex, and the specifications of heavy crossbows have also been uneven. These have begun to improve. The frontier troops have always had good combat capabilities, but their equipment is backward, and bronze wares are gradually beginning to be eliminated.
The last time Yang Gan inquired, the Central Army's equipment was all made of iron. Damn it, the ones left for him were all rubbish.
After all the equipment in the army is replaced, the bronze can be pulled out to make various tripods. It is quite troublesome to separate the main metal.
"I think you are crazy, spending so many slaves, food, grass, and money just to defeat Goguryeo."
Cao Wushuang never expected that Yang Qian would decide a battle so hastily.
Yang Gan looked helpless and really wanted to kick Cao Wushuang out. The comfortable custom-made rhinoceros saddle for one person is comfortable for one person, but for two people...
"Hey, master, how about I call a BMW and you can sit on the BMW instead? It's really uncomfortable for two people to sit together."
An arm stretched under Yang Gan's neck, and before he could react, he exerted force.
"Ah!! Master, master, you, you are going to strangle me." Yang Gan suddenly blushed.
"What? Are you uncomfortable sitting with me?" Cao Wushuang gradually let go of his arms.
Cao Wushuang's arms and thighs were as smooth as skin, but when she used force, her muscles became stringy. Sometimes Yang Gan was so scared that she would hit her chest with small fists.
Not to mention beating yourself to death, bleeding a few kilograms, and breaking a few ribs is still not a big problem.
Yang Gan said disgustedly, "The main reason is that there are all my subordinates behind me. It's not good for us to be like this."
Yang Gan shouted in his heart, "Get out of here quickly, I want to lie down and walk."
"Hmph, I think it's quite spacious when sitting on the back of a rhinoceros. Don't be too awkward."
Cao Wushuang leaned on the comfortable backrest, swinging his long legs continuously, ignoring Yang Qian's resentful eyes.
